I use Emacs across different machines and operating systems. I noticed that when I press
C-x C-b to get a list of all buffers, on some machines the list opens in the same window where the cursor is located and allows me to arrow through the list, using
ENTER to select and open the buffer I desire.
Yet, on other machines this list opens in the other window (I usually have at least two open) and even after I switch to that window using
C-x o, I am not able to arrow through the list, select and open.
How can I achieve the first type of behavior on the latter machines?
